- Q: New drills usually need sharpening before they can be used. Why?
- What you say does not exist, the new drill is not heavy grinding can be used; cutting edge is yes, the front angle is the drill bit of the spiral groove angle, it is impossible without the front angle, and the back angle is not 0 degrees, the peak angle is not big. It's only in the drilling that produces what I said before, so it's time to rub it again and use it again.
- Q: How do you drill a bit?
- A bit, including a cutter rod, a cutter rod tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E). The orientation of the short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end. In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
- Q: Is the drill fast to feed, easy to break, or slow to feed, easy to break?
- Therefore, the drill feed should be moderate, not only to ensure good broken, but also to ensure that the drill bit of cutting time.
- Q: How much is an alloy drill bit?
- Depends on what size and brand and technical requirements you need. I have no specific answer to that. You want a specific request for me
- Q: Tap with 5 taps. How many drills are drilled?
- Calculation formula:The workpiece is a brittle material (cast iron, bronze, etc.): the bore diameter is D=d- (1.04 to 1.08) tThe workpiece is made of plastic material (steel, copper, etc.): bore diameter is D=d-tD: nominal diameter of thread, t: pitch, unit: mm
- Q: Why can't the tap be nitrided? Drill bits are available.
- Many imported taps are coated now. In addition to TiN, there are TiCN, TiAlN.
- Q: How big is the screw hole at the back of the torch chuck? Is it a rebound?
- Usually around M5 or M6.
- Q: What does the cutting depth of the drill mean 3D?
- For example, 3D, the drill diameter is 20MM, then the effective drilling depth is 60MM, but the actual standard bit slot length must be about 80mm, because we should consider the chip space!!
- Q: What is the geometric angle of the drill bit?
- The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..
- Q: How do we drill a tile with a thickness of 5mm glazed, without a glass bit, only the impact bit? What's up? The brick is attached to the wall!
- If the tiles under not hollow cement, Tim is very full, can not grasp, if you should buy a special tile bit, namely triangular bits, it does not produce tremor phenomenon, easy positioning, cut resistance, opening soon, there are the ordinary chuck used on an electric drill to need to pay attention to slow speed in particular, is just beginning to open and slow speed when wearing. When in use, add coolant (not too much, but keep adding water). Drilling can be done on hard materials such as glass, stone and tile. 3MM-16MM have, but don't drill edge or side (away from 2 cm above tile seam), or to use the glass or diamond drill hole, is used to watch the speed slower (800-1000 revolutions per minute or so), continue to water cooling (don't need too much, but continue to add water) non dry drilling! High temperature friction, causing serious wear and tear, affecting the use effect!
